Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, specifically to a shock-absorbing connection component for an atomizer air pump. Background Technology

[0002] A nebulizer is a device that atomizes a solution and has wide applications in medical, industrial, and other fields. Nebulizers are typically used in medical or home environments. With technological advancements and increasing user demands, modern nebulizers are increasingly focusing on vibration reduction and noise reduction performance during the design and manufacturing process.

[0003] During continuous operation, the atomizer's core component—the air pump—operates at high speed and frequently. This intense mechanical action inevitably causes a certain degree of vibration in the entire device. This vibration not only affects the atomizer's operational stability but can also negatively impact the surrounding environment and user experience, such as causing noise interference or slight displacement of the platform on which the atomizer is placed. Furthermore, traditional methods of connecting the air pump to the lower shell mostly rely on mechanical components such as springs or clips for secure installation. However, the operation process is complex and cumbersome, and springs and clips are prone to loosening or damage under prolonged stress. Another method uses a plug-in connection structure, where an elastic element is inserted into a hollow cylindrical structure at the bottom. However, the elastic element and the hollow cylindrical structure are often mating cylinders, resulting in direct contact and limited shock absorption. Summary of the Invention

[0004] The purpose of this invention is to provide a shock-absorbing connection assembly for an atomizer air pump to solve the above-mentioned problems.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A shock-absorbing connection assembly for an atomizer air pump is provided for connecting the atomizer housing and the air pump assembly. The shock-absorbing connection assembly includes a mounting plate, an elastic connector, and a mounting base. The air pump assembly is fixed to the mounting plate. The mounting base is disposed on the inner bottom surface of the housing and has an accommodating space inside. The elastic connector includes an upper connecting part, a first deformation support part, a lower connecting part, and a second deformation support part arranged in sequence. The upper connecting part is connected to the mounting plate. The first deformation support part supports the upper connecting part and reduces the vibration force transmitted from the upper connecting part to the lower connecting part. The lower connecting part and the second deformation support part are inserted into the accommodating space of the mounting base. The second deformation support part supports the lower connecting part and reduces the vibration force transmitted from the lower connecting part to the mounting base. The lower connecting part includes a connecting post with a plurality of cantilever ribs evenly distributed circumferentially on the connecting post. The cantilever ribs extend radially from the side wall of the connecting post and abut against the inner side wall of the mounting base.

[0007] As a further improvement of the present invention, the cantilever bar includes a connecting end and an abutting end. The connecting end is connected to the connecting column, and the abutting end abuts against the inner wall of the mounting base. The end of the cantilever bar near the first deformation support is provided with a chamfer, and the end of the cantilever bar near the second deformation support is provided with a chamfer.

[0008] As a further improvement of the present invention, in the axial direction, the plane where the abutting end is located has an inclined angle relative to the axial direction. The inclined angle is used to facilitate the lower connecting part entering the mounting base. The end of the abutting end near the first deformation support part is far away from the connecting column, and the end of the abutting end near the second deformation support part is close to the connecting column.

[0009] As a further improvement of this utility model, in the axial direction, the plane where the abutting end is located and the connecting column make an angle of 1 to 2°.

[0010] As a further improvement of this utility model, within the accommodating space of the mounting base, the inner sidewall of the mounting base has the same inclination angle as the plane where the abutment end is located.

[0011] As a further improvement of this utility model, the vertex of the abutting end is higher than the top surface of the mounting base, or the vertex of the abutting end is flush with the top surface of the mounting base.

[0012] As a further improvement of this utility model, the abutting end and the inner circular wall of the mounting base are subjected to an interference fit.

[0013] As a further improvement of this utility model, four cantilever ribs are provided on the connecting column.

[0014] As a further improvement of the present invention, the structure of the first deformation support part is the same as that of the second deformation support part. The first deformation support part includes a contraction section, a throat and an expansion section arranged in sequence. The diameter of the throat is smaller than the diameter of the contraction section and the diameter of the expansion section. The connection between the throat and the contraction section is arc-shaped, and the connection between the throat and the expansion section is arc-shaped. In the axial direction, the arc is an inwardly concave arc.

[0015] As a further improvement of this utility model, the second deformation support part and the inner circular wall of the mounting base are fitted with a clearance.

[0016] The beneficial effects of this utility model are as follows:

[0017] The above structure uses flexible connectors to connect the air pump assembly to the lower shell, cantilever ribs to improve shock absorption and noise reduction, and the first and second deformation support parts to improve the overall stability of the machine. It also simplifies the installation process and makes disassembly easy. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0025] If the description of this utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.), then the directions involved need to be defined. For example, "To clearly express the position and direction described in this utility model, the operator of the instrument is used as a reference, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the paper can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not required.

[0026] A shock-absorbing connection assembly for an atomizer air pump, used in an atomizer, such as... Figures 1-2As shown, the atomizer includes a housing, an air pump assembly 2, and a shock-absorbing connection assembly. The air pump assembly 2 and the shock-absorbing connection assembly are disposed inside the housing. The housing includes an upper shell (not shown in the figure) and a lower shell 1 connected together. The air pump assembly 2 generates air pressure by driving a piston to reciprocate through high-speed rotation of a brushless motor. The shock-absorbing connection assembly is used to connect the housing of the atomizer and the air pump assembly 2.

[0027] The shock-absorbing connection assembly includes a mounting plate 3, elastic connectors 4, and mounting bases 5. The air pump assembly 2 is fixed on the mounting plate 3. There are several mounting bases 5, which are located on the inner bottom surface of the outer shell. Each mounting base 5 has an accommodating space 501 inside. There are several elastic connectors 4, and the number of elastic connectors 4 corresponds one-to-one with the number of mounting bases 5. The positions of the elastic connectors 4 and the mounting bases 5 also correspond one-to-one. One end of each elastic connector 4 is connected to the mounting plate 3, and the other end of each elastic connector 4 is inserted into the accommodating space 501 inside the mounting base 5. The accommodating space 501 is a cylindrical deep hole that mates with the lower end of the elastic connector 4. The mounting base 5 is used to position and fix the elastic connectors 4, thereby achieving the installation and fixation of the air pump assembly 2 and ensuring the smooth operation of the air pump assembly 2.

[0028] As one embodiment of this utility model, the elastic connector 4 is an elastic structure. Specifically, the elastic connector 4 can be made of materials such as silicone or rubber.

[0029] like Figure 3As shown, the elastic connector 4 includes an upper connecting part 41, a first deformation support part 42, a lower connecting part 43, and a second deformation support part 44 arranged in sequence. The upper connecting part 41 is connected to the mounting plate 3. The first deformation support part 42 and the second deformation support part 44 can deform, increasing the strength of the elastic connector 4 and making it less prone to collapse. The first deformation support part 42 supports the upper connecting part 41 and reduces the vibration force transmitted from the upper connecting part 41 to the lower connecting part 43. The lower connecting part 43 and the second deformation support part 44 are inserted into the receiving space 501 of the mounting base 5. The second deformation support part 44 supports the lower connecting part 43 and reduces the vibration force transmitted from the lower connecting part 43 to the mounting base 5. The lower connecting part 43 includes a connecting post 431, on which several cantilever ribs 432 are evenly distributed circumferentially. The cantilever ribs 432 extend radially from the side wall of the connecting post 431 and abut against the inner side wall of the mounting base 5. The connecting post 431 is inserted into the receiving space 501 of the mounting base 5, and the cantilever ribs 432 abut against the inner side wall of the mounting base 5. During the vibration of the air pump, the cantilever ribs 432 can effectively alleviate the resonance problem caused by the operation of the whole machine, reduce the vibration force transmitted to the lower shell 1, and at the same time play a role in shock absorption and noise reduction, as well as realize the connection and fixation of the elastic plug 4 to the shell. Through the above-mentioned elastic plug 4 structure, multi-level shock absorption is achieved and resonance is suppressed.

[0030] As an embodiment of this utility model, the cantilever rib 432 includes a connecting end 4321 and an abutting end 4322. The connecting end 4321 is connected to the connecting column 431, and the abutting end 4322 abuts against the inner wall of the mounting base 5. The length of the abutting end 4322 is less than the length of the connecting end 4321. A chamfer 4323 is provided at one end of the cantilever rib 432 near the first deformation support part 42, and a chamfer 4323 is provided at one end of the cantilever rib 432 near the second deformation support part 44, thereby forming an approximately triangular structure at both ends of the cantilever rib 432, which has a certain guiding effect and is convenient for installation into the mounting base 5.

[0031] As an embodiment of this utility model, in the axial direction, the plane where the abutment end 4322 is located has an inclined angle relative to the axial direction. The inclined angle is used to facilitate the lower connecting part 43 entering the mounting base 5. The end of the abutment end 4322 near the first deformable support part 42 is away from the connecting post 431, and the end of the abutment end 4322 near the second deformable support part 44 is close to the connecting post 431. Specifically, the purpose is, on the one hand, to facilitate the installation of the lower connecting part 43, and on the other hand, when the air pump vibrates and falls, even if the elastic plug 4 slides away from the mounting base 5, the lower connecting part 43 can still smoothly enter the mounting base 5 due to the effect of the inclined angle.

[0032] Specifically, in the axial direction, the plane where the abutment end 4322 is located makes an angle of 1 to 2° with the connecting post 431, and this angle can be achieved during the drafting process.

[0033] Based on the aforementioned inclined abutment end 4322, within the accommodating space 501 of the mounting base 5, the inner sidewall of the mounting base 5 has the same inclined angle as the plane where the abutment end 4322 is located, which also facilitates installation and guides the descent.

[0034] After installation, a chamfer 4323 of the cantilever rib 432 extends out of the mounting base 5. That is, the vertex of the abutting end 4322 is higher than the top surface of the mounting base 5, or the vertex of the abutting end 4322 is flush with the top surface of the mounting base 5. This maximizes the contact length between the cantilever rib 432 and the inner wall of the mounting base 5, forming a continuous surface contact, increasing the vibration transmission path impedance, and improving the vibration reduction and noise reduction effect.

[0035] In one embodiment of this utility model, the connection between the connecting end 4321 and the connecting column 431 adopts a rounded transition to optimize stress distribution and enhance connection strength. All other corners of the cantilever rib 432 are rounded to eliminate sharp corner interference, reduce assembly resistance for easier assembly, effectively block the transmission path of vibration waves, and have better vibration reduction and noise reduction effects.

[0036] As an embodiment of this utility model, the abutting end 4322 and the inner circular wall of the mounting base 5 are subjected to an interference fit, with an interference amount of 0.1 to 0.2 mm (the interference amount here is: twice the distance between the axis of the connecting column 431 and the plane where the abutting end 4322 is located minus the inner diameter of the mounting base 5), to avoid noise caused by the collision between the cantilever rib 432 and the mounting base 5.

[0037] As one embodiment of this utility model, four cantilever ribs 432 are provided on the connecting column 431 to cope with forces in multiple directions.

[0038] As one embodiment of this utility model, such as Figure 4 As shown, a mounting hole 31 is provided on the mounting plate 3, and the mounting hole 31, the elastic connector 4, and the mounting base 5 are coaxially arranged. The upper connecting part 41 includes an annular groove 411, and the upper part of the upper connecting part 41 can pass through the mounting hole 31. The upper connecting part 41 forms a fitting structure with the mounting plate 3 through the annular groove 411. The wall of the mounting hole 31 is arc-shaped, and the thickness of the mounting plate 3 is greater than the axial groove depth of the annular groove 411. When the mounting plate 3 is fitted into the annular groove 411, it is fixed by the elastic force of the elastic connector 4.

[0039] In one embodiment of this utility model, the upper connecting part 41 further includes a guide section 412 disposed above the annular groove 411. The guide section 412 is frustum-shaped or conical. The diameter of the mounting hole 31 is larger than the minimum diameter of the guide section 412, and the diameter of the mounting hole 31 is smaller than the maximum diameter of the guide section 412. The diameter of the end of the guide section 412 near the annular groove 411 is larger than the diameter of the end of the guide section 412 away from the annular groove 411. The guide section 412 guides the upper connecting part 41 through the mounting hole 31 and facilitates its insertion into the mounting hole 31. A portion of the mounting plate 3 beside the mounting hole 31 is inserted into the annular groove 411, thereby achieving the connection and fixation between the elastic connector 4 and the mounting plate 3 and improving the connection stability.

[0040] As an embodiment of this utility model, for ease of use, an extension section 413 is formed by extending from the guide section 412 away from the annular groove 411. The diameter of the extension section 413 is smaller than the diameter of the mounting hole 31. In use, the extension section 413 first passes through the mounting hole 31. Due to the elasticity of the elastic connector 4, the guide section 412 deforms during the process of passing through the mounting hole 31 until it completely passes through the mounting hole 31. After completely passing through the mounting hole 31, the guide section 412 loses the external force restriction and returns to its original shape. The mounting plate 3 around the mounting hole 31 is inserted into the annular groove 411 to form a stable connection structure.

[0041] In one embodiment of this utility model, the structure of the first deformable support portion 42 is consistent with the structure of the second deformable support portion 44. Specifically, the first deformable support portion 42 is hourglass-shaped and includes a contraction section 421, a throat 422, and an expansion section 423 arranged in sequence. The diameter of the throat 422 is smaller than the diameter of the contraction section 421 and the diameter of the expansion section 423. The first deformable support portion 42 is the main support point of the entire elastic connector 4. The diameter of the contraction section 421 gradually decreases from the upper connecting portion 41 to the throat 422, and the diameter of the expansion section 423 gradually increases from the throat 422 to the lower connecting portion 43. The throat 422 has the smallest diameter. The triangular structure has high stability, and the connection between the throat 422 and the contraction section 421 and the expansion section 423 is arc-shaped. In the axial direction, the arc is an inwardly concave arc, which enhances the strength of the entire elastic connector 4 and makes it less prone to collapse. During the vibration of the air pump assembly 2, the first deformation support 42 and the second deformation support 44 can deform, reducing the vibration force transmitted to the lower structure and achieving the effect of vibration reduction and noise reduction.

[0042] In one embodiment of this utility model, the second deformation support 44 and the inner circular wall of the mounting base 5 are fitted with a clearance, the clearance being 0.4 to 1 mm (the clearance here is the inner diameter of the mounting base 5 minus the maximum diameter of the second deformation support 44), to provide deformation space for it.

[0043] As one embodiment of this utility model, such as Figure 5 As shown, there are three mounting bases 5 arranged in a triangle. The number and position of the elastic plugs 4 correspond one-to-one with the mounting bases 5, and the number and position of the mounting holes 31 correspond one-to-one with the elastic plugs 4.

[0044] The shock-absorbing connection assembly for the atomizer air pump provided by this utility model abandons the traditional connection method of connecting the air pump and the lower shell 1 using springs or snap-fit ​​connectors. Instead, it uses an elastic plug connector 4 to connect the air pump assembly 2 and the lower shell 1, and uses a cantilever rib 432 to provide elastic support, effectively absorbing vibration energy and improving the shock absorption and noise reduction effect. The first deformation support part 42 and the second deformation support part 44 improve the overall stability of the machine, simplify the installation method, and make it easy to install.

[0045] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0046] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
